Gringing Machine vacuum cover

I use my grinding mini machine at home and a lot of dust is generated every time when I work with it. So I finally found some time to make a vacuum cover to connect with my vacuum cleaner. I printed and tested the cover successfully enough. The volume of dust was reduced dramatically. The grinding machine I use is Sturm BG60075 (75 mm grinding stone diameter). There are many identical machines with the same dimensions, so the cover could be used (may be with the minor modifications).
Hose holder is designed for 32mm vacuum cleaner handle (with small cone from 32 to 33 mm)
